Define the concentration of hcl in a solution by titrations

Reference no: EM13192853

You measured the concentration of Hcl in a solution by titrations using different indicators to find the end point. Is the difference between indicators 1 and 2 significant at the 95% confidence level?

Indicator 1 is Bromothymol blue of mean Hcl concentration (+/- standard deviation) = 0.09565 +/-0.00225 and # of measurements = 28

Indicator 2 is methyl red of mean Hcl concentration (+/- standard deviation) = 0.08686 +/- 0.00098 and # of measurements = 18
